EGG-BOX. v

tons of that kind in which "a flexible cover is provided and formedwith a flap or-hp which is inserted inside of the front wall of the box or carton after the latter is filled with eggs. Ordinarily, the said flap or l1p is inserted between the said front 'wall and the filler which is usually employed for holding the eggs in place.

The principal object of my invention is to provide an'integral sealing tab for the cover of a box or carton of this kind, having means for holding it in the plane' of the flap or lip while the box is being manipulated, but the said means being adapted to be broken as soon as it is'desired to seal the box,

sist of a small portion of the paste boardor other material from which the box is made) permitting the tab to swing outward and into position to be glued or otherwise fastened to the outer surface of the front wall of the box, thereby securely holding the cover in closedposition.

To the foregoing and other useful ends my invention consists in matters hereinafter set forth and claimed.

In the accompanying drawings-Figure l is a perspective ofan egg box or carton provided with a sealing tab embodying the principles of my invention, the said box or carton being shown with its cover in closed position, and with the said tab glued or otherwise fastened to the outer surface of the front wall of the box. Fig. 2 is an enlarged fragmentary view of a portion of the cover of said box or carton, showing the tab with its retainingportion unbroken, whereby said tab is maintained in the plane of the flap or lip of the cover until such time as it is desired'to seal the box, thus precluding any accidental or premature bending of the tab, and preventing it from getting in the way while the box is being manipulated, previous to. and during the filling of the same. F ig. 3 is a section on line 3-3 in Fig. 2, indicating in dotted lines the position of the Specification of Letters Patent; Patentgd (Oct, 12, 1915,

tab after its retainer is broken and after the tab is swung outward.

As thus illustrated, my invention comprises a foldable box or carton having a front wall A and a cover 13, the said box being rectangular in shape. The back wall and bottom of-the box are flat, and the ends C. have creases or fold lines 0, whereby the said ends fold inward upon the bottom of the box. For this purpose, the front wall A is also provided with oblique creases or fold lines a which permit the said front wall to fold inward upon the bottom of the box. The saidends fold upon the front wall, and thenthe back wall folds down upon the said endsz and the cover 13 extends forward with its flap or lip b, all substantially ina horizontal plane. The said flap 5 extends insideof the front wall A, when the box is closed, and is usually inserted between this wall and the well known filler by which the eggs are held in place.

My invention relates to the method of sealing the said cover B in closed position.

- the breaking of said means (which may-con- For this purpose, a tab 6 is out from the the paste board. During manipulation of the box this retainer 6 holds the tab 6 against premature bending or displacement, and prevents the tab from getting in the way or interferingwith the operation of filling and closing the box. When the cover is brought downward, and before the flap or lip b is inserted inside of the front wall, the retaining portion 6 is broken, thus allowing the tab 11 to slide down outside of the front wall A, as shown in Fig. 1; and by means of glue or some other adhesive, the said tab can then be secured in place upon the outer surface of the said front wall. This adhesive can be previously applied to the said tab, so that a moistening of the same will render it suitable for application to the surface of the front wall. But I do not limit myself to any particular means for securing the tab 6 to the outer surface of the front wall A, for the purpose of sealing the box, as this can be accomplished by mechanical means or fastening devices as well as by an adhesive.

From the foregoing it will be seen that by my invention I provide an integral sealv ing device "for securing the cover ofthe box which the flap or lip bis folded at right angles to the body of the cover. Asshovvn,

the said tab 5 has the shape of a half moon, but it maybe of any suitable form, and I do not limit myself to the exact construction shown and described. What I olaim as my invention is 1. In a paper box, a cover provided With a flap on its front edge adapted for engagement With the inner side of the front Wall of the box and having a sealing tab formed therein, said sealing tab having a hinge connection and a readily breakable connection with said flap, whereby a partly formed tab is provided Which will retain its alinement with said flap until the breakable connection is separated.

2. In a paper box, a cover provided With a flap on its front edge adapted for engagement With the inner side of the front Wall of the box and having a sealing tab formed therein, said sealing tab having a flexible I connection with said cover on the folding line of said flap to form a hinge, and having a readily breakable, connection With the body of said flap, whereby a partly formed tab is provided which will retain its alinement with the body of the flap until the breakable connection is separated.

and said tab being formed by cutting throughsaid flap in a plurality of places leaving a long connection With said cover on the bending line of the flap to form? ahinge, and a breakable connection With the body of the flap, whereby said flap can be bent Without dislocating the tab therefrom in order that the tab may be positioned With the flap, and said breakable connection separated to permit fastening of said tab and use thereof as a sealing member against the outer face'of said front Wall.
